Afnwocen' /Nvevaw Patented Nov. 22, 1938 UNITED STATES PATENT OFFICE Application December 1, 1936, Serial No. 113,746 In Italy March 3, 1936 3 Claims.

My present invention has for its object to provide a metal tube structure or scaiolding with wood iloors, and with walls and roof of corrugated iron, or the like.

According to this invention, on a metal skeleton of tubes suitably connected together floors of wood boards are mounted, connected to the horizontal tubes by suitable union pieces, and further vertical walls and roofs are mounted, made of corrugated iron or corrugated plates by means of suitable fixing devices.

The invention is illustrated in the annexed drawing in which:

Fig. 1 is a total view of part of a shed of metal tube structure according to the invention,

Fig. 2 a detail View in vertical section of a device for fixing vertical corrugated plates,

Fig. 3 a front View corresponding to Fig. 2,

Fig. 4 a View similar to Fig. 2 showing a modification of the strap co-operating with the proilled or h-shaped section iron, and showing furthermore a part of a support bracket, Fig. 5 is a front elevation of the strap shown in Fig` 4,

Fig. 6 shows the same in side elevation in full lines, whilst it shows in dotted lines the working position of the strap.

Fig. l shows a part of a shed for aeroplanes or the like, built of vertical metal tube elements I and horizontal metal tube elements 2. On the sides of the shed vertical walls 3 ofvcorrugated metal or like plates are mounted, whilst on the beams and horizontal tubes 2, respectively, iloors 4 are mounted.

The metal tube structure is covered by a roof 5, of corrugated metal, or like plates.

In Figs. 2 and 3, an h-shaped section iron 6 a plate 3 with vertical corrugations is placed, held in position by a Strap l Xed to a leg 8 of the h-shaped iron by means of a plate 9 and a screw I0.

Member 'l substantially consists of a bar or rod bent to follow the outline of section iron 6 as indicated in Fig.V 2. The member 'l terminates at the top in a bent end Il adapted to x the plate 3 on the upper part I2 of the section iron 6.

At the bottom the member 'I has an extension I3 the end I4 of which bears on the lower corrugated plate 3 also provided with vertical corrugations.

The section irons 6 are placed horizontally at a vertical distancev equal to the length of the corrugated plates designed for providing the Wall of a structure or building, for instance a shed as shown in Fig. 1 where to the standards I vertical corrugated metal plates 3 are xed by means of the section irons 6, which latter are supported by brackets I5.

In Figures 4, 5 and 6 a second form of said strap member is shown. On the h-shaped section iron ti supported on a bracket I5 a strap 5 I6 is flxed which normally has the shape shown in full lines in Figures 5 and 6, and takes the form shown in Figure 6 with dotted lines (and in Fig. 4 with full lines) when it is placed in position on the h.shaped member, and deformed by a suitable tool, for instance a hammer. The end il of member I6 has the same purpose as the end Il of said member l.

The lower corrugated plate 3, in this case, is only kept in place by the lower Wings of the h-Shaped section iron, whilst the upper corrugated plate 3 is positively kept between the end Il of iron It and the upper part I2 of the section iron Ii.

The invention has been described and illustrated in some preferred forms of realization, but in practice it is susceptible of numerous structural modications within the limit of the following claims.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

l. A device for fastening sheet material com prising, a member having a top portion and a straight leg portion and a horizontal portion and a leg depending therefrom so as tobe h-shaped in section adapted to be positioned between the ends of two sheets in such a manner that the normal horizontal portion of the h-shaped member is between the ends of the sheets, means associated with said member adapted to urge the end of one of said sheets into clamping engagement with the normal top portion of the h-shaped member, and said means extending along the horizontal and depending leg portions of said member for urging the end of the other sheet into clamping engagement with one of the legs of said h-shaped member.l

2. A device for fastening sheet material as claimed in claim 1 wherein the means for urging the last mentioned sheet into engagement with the h-shaped member comprises a strip fixed to the depending leg-portion of the h-shaped member by means of screws and a counter plate.

3. A device for fastening sheet material as claimed in claim 1 wherein the means for urging the rst mentioned sheet into engagement with the normal top portion of the h-shaped member comprises a bent strap adapted to embrace the depending leg of the h-shaped member.
